How can DJGPP's FSDB (full screen debugger) read the descriptor
tables? I mean when you press alt-g or alt-i. I want my own
program to display stuff from them, but doing a sidt/sgdt to
a struct { ushort limit; ulong address; } and the referring
to the address just crashes under Win98. Well, that's what
I expected, since those tables are (should be?) protected by
the OS, and are probably mapped differently anyway. So how
does FSDB do it then?
